方法一：private void button1_Click(object sender, RoutedEventArgs e) { WebClient webClientImgDownloader = new WebClient(); webClientImgDownloader.OpenReadCompleted += new OpenReadCompletedEventHandler(webClientImgDownloader_OpenReadCompleted); webClientImgDownloader.OpenReadAsync(new Uri("http://dilbert.com/dyn/str_strip/000000000/00000000/0000000/000000/80000/5000/100/85108/85108.strip.print.gif", UriKind.Absolute)); } void webClientImgDownloader_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e) { BitmapImage bitmap = new BitmapImage(); bitmap.SetSource(e.Result); // ERROR HERE! image1.Source = bitmap; 方法二： //将本地资源文件到Image控件上，图片的Bulid Action属性要设置成Content Uri uri = new Uri("/Images/meinv.jpg", UriKind.Relative); //直接将网络图片显示到Image控件上 Uri uri2 = new Uri("http://www2.ff369.com/tupian/201103/010/1.jpg",UriKind.Absolute); ImageSource imgSource = new BitmapImage(uri); image1.Source = imgSource; //当资源图片资源文件的属性是Resource时，使用下面的方法将图片呈现到Image控件上，但是不建议使用这种方法 //在网上查看资料说将图片以Resource会造成闪屏 Stream stream = App.GetResourceStream(new Uri("/DemoCode2;component/Images/meinv.jpg", UriKind.Relative)).Stream; BitmapImage bitmap = new BitmapImage(); bitmap.SetSource(stream ); // ERROR HERE! image1.Source = bitmap;
}
